Hippo-sized chicken. You can change the size, but not the nature. Hippos are very aggressive, and even when it is the size of a chicken it could do a lot of damage - especially if there were six of them!

My significant other says he would rather fight the giant chicken, not because it would be easier but because it would be awesome, kind of like fighting a dinosaur. If it's the same mass as a hippo (a couple of tonnes) but chicken shaped it would be really, really big. I guess the fact that a chicken can only see out the sides of its head and not to the front might work in your favour, and if you could take out one of its legs it would fall over.

Little hippos would be mean and have a vicious bite to them, but to have the same mass as a chicken (which really don't have all that much to them under the feathers) they'd be pretty small, like guinea pig sized, which doesn't seem all that much of a threat, especially if you have a big pair of stompy boots.

Hippo sized chicken. One enemy is easier to defeat, no matter the size. I would rig something to trip it over, get it on it's back and it would go in to a nice little chooky trance. Then I would pet it and pat it and take it home as my pet. I love chhoks. (Note to self . . . you're gonna need a LOT of chook food!)

I still don't have an answer to this question, but in the early 90's, my husband took our eldest daughter ( who was 16 or 17 at the time,) to Zimbabwe, on a 2 or 3 day canoe trip, with the river full of hippos! NO, & no-one fell out of the boat! I wouldn't go with them, because it meant not having a shower for 2/3 days/nights, & sleeping in tents on the riverbanks! I love all your answers to this question! Very funny.

Initially I thought a hippo sized chicken, because I understand chickens and would know how it is likely to behave. I have changed my mind to six chicken sized hippos because at least I could escape by climbing a tree.
I suppose I could escape a giant chicken by swimming...so hopefully if I am ever attacked by one I will be beside a body of water.
